In the apparatus according to the above-mentioned disclosure, the set value preset in the storage unit for comparison with the measured value of the measuring instrument is set directly for each site or the monitoring center. It is set by remote control. In this case, at the installation site of each elevator, the usage state of the elevator is different, so the average set value initially set is not always appropriate at that site, and the measured value of the measuring instrument is stored in the storage unit. Elevator equipment may deteriorate and need to be replaced before the set point is reached.

For such a site, the set value to be set and stored in the storage unit needs to be made lower than before from the next time, but in the disclosed device, the maintenance personnel directly visit the site. It is necessary to change the set value by using the monitoring center or check the deterioration status of each elevator equipment at each site at the monitoring center and then set the changed set value for the elevator equipment at that site. There was a problem that was complicated.

The present invention has been made in view of the current state of operation status monitoring of elevator equipment of this type as described above, and the purpose thereof is to appropriately elapse operating time corresponding to each site where the elevator is installed. It is another object of the present invention to provide an operation status reporting device for an elevator device, which is capable of reporting a change in the elevator device.

[0006]

In order to achieve the above object, the present invention provides a measuring instrument for measuring at least one of the number of times of operation and the operating time of an elevator device, and a measured value of this measuring instrument in a storage section.

Further, the comparator 6 has a function of comparing the count value of the frequency meter 4 with a reference set value written in the storage unit 8 in advance, and outputting a notification signal when the count value reaches the reference set value, and It also has the function of the writing means of the present invention for writing the count value of the frequency meter 4 at the time of inputting the exchange signal into the storage unit 8 as a new reference set value by inputting the exchange signal. Similarly, the comparator 7 has a function of comparing the integrated count value of the integration time meter 5 with the reference set value written in the storage unit 9 in advance, and outputting a notification signal when the integrated count value reaches the reference set value. And by inputting the exchange signal,
It has a function of the writing means of the present invention for writing the integrated count value of the integrated time meter 5 at the time of input of the exchange signal in the storage unit 9 as a new reference set value. The alarm device 10 has a function of transmitting the notification signals of the comparators 6 and 7 to a monitoring center (not shown) via a communication line.

Next, the operation of the embodiment having such a configuration will be described.

When the elevator car is operated to rise, an unillustrated up operation relay is energized to close the contact 2 and when the car is stopped, the contact 2 is opened and the car is moved down. The contact 3 is opened when the down operation relay (not shown) is energized to close the contact 3 and stop the car. In the frequency meter 4, the contact point 2 as described above due to the operation of the car
And the number of times the contact 3 is closed, that is, the number of times the car is activated, and the counted value is recorded in the frequency meter 4. Similarly, the integrated time meter 5 cumulatively counts the closing time of the contacts 2 and 3, that is, the operating time of the car, and the integrated count value is recorded in the integrated time meter 5.

Further, the comparator 6 compares the count value of the frequency meter 4 with a reference set value which is preset and written in the storage unit 8, and when the count value of the frequency meter 4 reaches the reference set value, A notification signal is input to the reporting device 10. Similarly, the comparator 7 compares the count value of the integrated time meter 5 with a reference set value which is preset and written in the storage unit 9, and when the integrated count value of the integrated time meter 5 reaches the reference set value. , A notification signal is input to the reporting device 10. Thus, when the notification signal is input from the comparator 6 or the comparator 7, the alarm device 10 transmits the notification signal to the monitoring center via the communication line, and the operation relay of the elevator reaches the operating life. Report that it has been reached. Upon receiving this notification, the operator of the monitoring center dispatches a maintenance staff to the building where the elevator is installed, and has the maintenance staff check the degree of deterioration of the elevator operation relay including the contacts 2 and 3 and check the necessary parts. Replace with new parts.

Upon completion of the replacement of the required parts of the operation relay, the maintenance staff operates a button (not shown) provided in the input device 11 to input a replacement signal to the comparators 6 and 7. In this way, when the exchange signal is input to the comparator 6, the comparator 6 sets the count value of the frequency meter 4 at the time of input of the exchange signal in the storage unit 8 as a new reference set value. Proximity meter 4 is reset. Similarly, when the replacement signal is input to the comparator 7, the comparator 7 sets the integrated count value of the integration time meter 5 at the time of input of the replacement signal in the storage unit 9 as a new reference set value.
The integrated time meter 5 is reset.

Generally, an elevator has a considerably different operating condition depending on the building in which it is installed, and the operating life of the elevator equipment in the building also varies correspondingly. Therefore, even if an average reference set value is initially set in the storage unit 8 or the storage unit 9, the elevator is frequently operated over a long period of time depending on the building.
Before the number of start-ups and the operating time reach the respective reference set values, the contact 2 or the contact 3 of the operation relay deteriorates, resulting in an elevator requiring replacement. On the other hand, in other buildings, there are elevators that are not frequently used and the operating time is short, and the operating life of the contact 2 and the contact 3 of the operating relay is longer than the average reference set value in the elevator.

The embodiment is adapted to the actual operating state of such an elevator, and is written in the storage units 8 and 9 for the elevator equipment that frequently operates the elevator for a long time. If, for example, the contacts 2 and 3 are replaced before reaching the reference set value, the count value of the frequency meter 4 at the time of replacement is stored in the storage unit 8 and the integrated count value of the integration time meter 5 is stored in the storage unit 9 as a new reference set value. Written as For this,
From the next time on, based on the reference set value set in conformity with the operating condition of the elevator, the alarm device 10 will notify the monitoring center, and the parts including the contact points 2 and 3 of the operation relay will be sent at an appropriate time. The elevator equipment is replaced properly and efficiently. This is also the case when the elevator is infrequently operated and the operating time is short, and it is confirmed by maintenance that the operating life of the elevator equipment is longer than the set reference value. If the parts including the contacts 2 and 3 of the operation relay are replaced with different count values, the alarm device 10 will notify the monitoring center when the count value at the time of replacement is reached from the next time, and the parts of the operation relay will be notified. Can be replaced at the right time. And
In the embodiment, the reference set values for the storage units 8 and 9 are automatically changed when the elevator equipment is replaced. Therefore, the maintenance personnel can change the set values for each site or set each change at the monitoring center. There is no need to check the value and set a new setting value.

In the embodiment, the operation relay is taken as the elevator equipment, and the operation life is determined by measuring the number of times of closing and the closing time of the contact, but the present invention is limited to the embodiment. Not applicable, it can be applied to various types of elevator equipment such as various lamps other than operation relays and safety devices.The number of times the lamp is turned on and turned on, the number of times the safety device is turned on and off, the number of times each floor is opened and closed, etc. Can be measured and the operating life of each can be determined.

[0018]

As described in detail above, according to the present invention,
When replacing elevator equipment that has reached its operating life and has deteriorated,
By the writing means, the measured value of at least one of the number of times of operation and the operating time of the elevator equipment at the time of replacement is written in the storage unit as a new reference set value, so that the maintenance personnel can change the reference set value on site. There is no need to check the status of each elevator equipment from the monitoring center side and change the reference set value, and the optimum reference setting corresponding to the operating status of each elevator equipment automatically written in the storage section Based on the value, it becomes possible to efficiently replace each elevator device at an appropriate time.
